Gear Burrs

Gear Burrs


Gear burrs are a common phenomenon in the field of machining and gear manufacturing. These tiny, often overlooked imperfections can have a significant impact on the performance and lifespan of gears. In this article, we will explore the various aspects of gear burrs and their implications.

What are Gear Burrs?

Gear burrs are small, unwanted projections that occur along the edges or surfaces of gears during the manufacturing process. These burrs are typically formed due to the cutting or shaping of gears, leaving behind irregularities that can affect the overall functionality of the gear system.

The Formation of Gear Burrs

1. Inadequate Tooling: The use of worn-out or incorrect cutting tools can result in gear burrs. The lack of sharpness or improper tool geometry can cause the material to be displaced, leading to burr formation.
2. Machining Parameters: Incorrect machining parameters such as excessive speed, improper feed rates, or inappropriate cutting fluid can contribute to the formation of burrs.
3. Material Properties: Some materials are more prone to burr formation than others. Brittle materials or those with uneven hardness can increase the likelihood of burrs during the machining process.
4. Cutting Techniques: Different cutting techniques, such as milling or hobbing, can influence the formation and severity of gear burrs.

Implications of Gear Burrs

1. Reduced Performance: Gear burrs can interfere with the smooth engagement of gears, leading to decreased efficiency and increased friction. This can result in power loss, noise generation, and premature wear.
2. Increased Vibrations: The presence of gear burrs can cause vibrations within the gear system, leading to additional stress on the gears and other components. This can ultimately result in component failure or reduced system reliability.
3. Lubrication Issues: Gear burrs can disrupt the proper distribution of lubricants, causing inadequate lubrication in critical areas. Insufficient lubrication can accelerate wear and tear, leading to further complications.
4. Assembly Challenges: During gear assembly, burrs can hinder the mating of gears or cause difficulties in aligning the components correctly. This can impact the overall assembly process and increase the risk of misalignment.

Prevention and Removal of Gear Burrs

1. Proper Tooling Selection: Using high-quality and appropriate cutting tools can minimize the formation of gear burrs.
2. Optimal Machining Parameters: Employing the correct machining parameters, such as cutting speed, feed rates, and coolant application, can help reduce burr formation.
3. Material Considerations: Selecting materials with suitable properties can aid in reducing the occurrence of gear burrs.
4. Post-Machining Techniques: Implementing deburring processes such as grinding, filing, or abrasive blasting can effectively remove gear burrs and improve gear quality.


Gear burrs may seem insignificant, but their impact on gear performance and reliability should not be underestimated. By understanding the causes, implications, and prevention methods associated with gear burrs, manufacturers and engineers can strive towards producing gears of superior quality and functionality.
